GrimmSpeed StealthBox Cold Air Intake Black Subaru STI 2015-2017

The GrimmSpeed StealthBox Cold Air Intake is a hybrid cold air/short ram design that combines the advantages of both traditional intake designs. It features an air straightener to ensure accurate MAF sensor readings, and the MAF sensor is strategically placed inside the heat shield to isolate it from engine bay heat. The intake utilizes a custom reusable high-flow air filter with an integrated velocity stack for smooth incoming air. The sleek "StealthBox" heat shield design is inspired by the F-117 Nighthawk and looks great in the engine bay while protecting against heat. The product is made in the USA.
